Forcing efficacy

Posted on December 15, 2015 by ...and Then There's Physics

There’s a new paper, discussing climate sensitivity, by Marvel, Schmidt, Miller & Nazarenko called Implications for climate sensitivity from the response to individual forcings. Before I discuss the paper, I should really advertise the lead author’s blog, arguably one of … Continue reading →

Watt about Roger’s questions?

Posted on May 20, 2015 by ...and Then There's Physics

I haven’t done a Watt about post for quite some time, so thought I would repeat it just this once. Roger Pielke Sr has guest post on Watts Up With That claiming to present seven very inconvenient questions that Gavin … Continue reading →

Andy Lacis responds to Steve Koonin

Posted on April 10, 2015 by ...and Then There's Physics

I know Eli’s already posted Andy Lacis’s response to Steve Koonin on Judith Curry’s blog, but I thought it worth repeating. It’s a pretty impressive comment in terms of what it covers, so it’s worth reading in it’s own right. … Continue reading →

CO2 forcing observed from surface

Posted on February 26, 2015 by ...and Then There's Physics

I thought I would post this video illustrating the first time that a change in CO2 forcing has been observed from the ground. The paper is an Observational determination of surface radiative forcing by CO2 from 2000 to 2010 by … Continue reading →

Back to basics

Posted on October 25, 2014 by ...and Then There's Physics

Although I didn’t really think through starting this blog, one motivation was that I was aware that quite a lot of what was said about climate science in the blogosphere was simply wrong. I thought that if I could point … Continue reading →

Aerosols

Posted on February 16, 2014 by ...and Then There's Physics

I had been intending to write a post about aerosols, given what’s been said about them recently. In particular, Nic Lewis at the Parliamentary Select Committee said a couple of things that I wanted to check. Essentially he was arguing … Continue reading →

Forcings and feedbacks

Posted on December 27, 2013 by ...and Then There's Physics

William Connolley had a recent post about making stuff up, that discussed the linear relationship between temperature change and change in forcing (ΔT = λΔF). I commented that I had thought that this linear relationship was simply an approximation based … Continue reading →

And then there’s the energy imbalance

Posted on December 8, 2013 by ...and Then There's Physics

There are a few things I have been considering writing about, but since I’ve renamed the blog to be more explicitly physics orientated, I thought the first should at least reflect that change. There’s a recent paper by James Hansen … Continue reading →

Okay, Roger, an acknowledgement

Posted on October 24, 2013 by ...and Then There's Physics

I wrote, yesterday, a rather snarky – and insulting – post about what I thought was an embarrassing blunder by Roger Pielke Sr in his recent WUWT post. Roger responded with the following tweet Misinterpretation by @wottsupwiththat See http://t.co/fADmzTu23T and … Continue reading →

Watt is up with Roger Pielke Sr

Posted on October 23, 2013 by ...and Then There's Physics

I wasn’t going to write another post today but I’ve just come across a new Watts Up With That (WUWT) post by Roger Pielke Sr. The title of the post is Radiative Forcing, Radiative Feedbacks and Radiative Imbalance – The … Continue reading →
